Patent CA-2169198-A1 (CA)
Title: Tactile computer display for the blind
Inventor: TREMBLAY MARCO
IPC: G06F3/00
Filed: 1996-02-09
Abstract: This invention discloses a tactile display for computer to be used by blind people with finger reading skills.  The display is made of a plurality of independently inflatable dots called pixel, arranged in a dense matrix format. The matrix can display many lines of Brail characters or graphics.   The control of each pixel relies on the expansion of a substance heated by an electric element. Each pixel is made of a small cylinder containing the expansion substance.  The cylinders are closed up rigidly at the bottom end and by an elastic membrane at the top end.  The elastic membrane serves as the reading surface.  To raise a pixel, the corresponding electronic drivers are turned on to activate the pixel's heater.  As the substance contained in the cylinder heats up, it expands to stretch the section of the elastic membrane covering it.   The membrane then forms a bump of sufficient height to be sensed by the reader's finger.  As soon as the drivers deactivate the pixel's heater, the substance cools down and shrinks.  The elastic membrane is then pulled down making the surface flat again.  During normal operation, the drivers are successively activated in order to scan the whole surface of the display activating only the pixels that should be raised.  This technology is not only limited to be used by the blind but can also produce tactile feedback devices for virtual reality applications or to make various massaging devices.

Title: Computer method and apparatus for asynchronous ordered operations
Inventor: DOSHI KSHITIJ ARUN
IPC: G06F17/30
Filed: 1995-07-26
Abstract: A computer system having data organized in files, having a secondary storage for storing files, having a primary storage, and having one or more types of subsystems (file system implementations) for controlling transfer of files between primary storage and secondary storage. A subset of writes to secondary storage are performed using a Delayed Ordered Write (DOW) subsystem, as shown in the figure, which makes it possible for any file sys-tem to control the order in which modifications are propagated to disk. The DOW subsystem (30) con-sists of two parts. The first part is a specification interface, which a file system implementation or any other kernel subsystem can use to indicate se-quential ordering between a modification and some other modification of file system structural data. The second part of DOW subsystem is a mecha-nism that ensures that the disk write operations are indeed in accordance with an order store. DOW improves computer system performance by reduc-ing disk traffic as well as the number of context switches that would be generated if synchronous writes were used for ordering.

Patent CA-2177867-A1 (CA)
Inventor: FIGUEIREDO ANTONIO ALBINO
IPC: H02H9/06
Filed: 1996-05-31
Abstract: A surge protection cartridge adapted for use with a double-sided modular connector block system. The protector cartridge advantageously mounts in the front or rear of a connector module of the connector block in a variety of orientations in order to protect an entire row of terminations on the block. Two L-shaped brackets adapted to couple to a mounting bracket of the connector block form an internal ground bus within the protector cartridge. The brackets include a series of cantilever connecting clips which couple directly to the surge protection devices. Spring contacts having similar cantilever clips couple the remaining leads of the surgeprotection devices and the terminals of the connecting block which are to be protected. Each individual spring contacts is seated within an individual insulated well of the cartridge housing. The feature maintains a substantial insulation resistance between adjacent terminals of the housing and advantageously preventsshorting between adjacent terminal leads caused by the collection of moisture. A set of protrusions within the cartridge housing corresponding to the wells engage the spring contacts to force correct seating position. An exclusion feature attached to the cartridge housing ensures that only protection cartridges having a sufficient number of protection devices may be inserted within certain sized connector modules.

Title: Telescoping needle shield
Inventor: BRIMHALL GREG L
IPC: A61M5/32
Filed: 1996-06-05
Abstract: A needle assembly is provided with a needle securely mounted to a needle hub. A shield assembly includes a plurality of telescoped tubes concentrically surrounding the needle. One of the telescoped tubes is securely connected to the needle hub. The other tubes in the assembly may be slid away from the needle hub. The tubes have combined lengths to enable complete shielding of the needle when the tubes are telescopingly extended. The distal-most tube, when the tubes are telescopingly extended, includes a tip guard which resiliently moves over the distal tip of the needle as the shield assembly is fully extended. The distal-most tube, when the tubes are telescopingly extended, of the shield assembly frictionally engages a catheter adapter to prevent withdrawal of the needle from the shield assembly until the tubes are fully telescopingly extended. As full shielding of the needle is reached, the shielded needle is separated from the catheter adapter.

Title: Programmability for motor-vehicle turn signaling
Inventor: WADLINGTON BEN JR
IPC: B60Q1/40
Filed: 1995-06-06
Abstract: Individual/driver-defined durations of lever-off automotive turn signaling are provided in response to the application of one or more "taps" to a vehicle's signal lever (S1). A counter (3 or 4) is incremented for each tap detected by monitoring circuitry. A non-zero tap count imparts the timing out of lever-off signaling. A timed-signaling duration is the sum of either one or a series of predetermined-length, tap-associated duration segments. As each segment is timed out, the tap counter (3 or 4) is decremented. On-the-fly extensions of the duration are enabled. Reset (7) provisions and the transparent invoking means preclude conflicts with non-timed signaling.

Title: Method and arrangement for producing a foam-formed fibre or paper web
Inventor: REINER LENNART
IPC: D21F11/00
Filed: 1995-07-12
Abstract: Method of producing a foam-formed fibre or paper web, whereby a foamed fibre dispersion is formed by dispersing natural and/or synthetic fibres in a foamable liquid comprising water and a tenside in a dispersion vessel (111) and by conveying the foamed fibre dispersion to a wire (118) on a paper machine. The foamed liquid which is removed through the wire (118) is conveyed to a closed foam tank (128) in which a draining of the liquid to the bottom of the tank occurs, whilst the lighter foam is collected in the top of the foam tank. Liquid from the bottom of the foam tank is led to the dispersion vessel (111) via a first pipeline (129), whilst foam passes to the dispersion vessel via a second pipeline (130) in the top of the foam tank where the fibres are added and dispersed in the foamable liquid.
